United States Patent SUPPORT BRACKET FOR COVER BOARD Donald J. Bauer, Norwalk, Ohio Application April 18, 1955, Serial No. 501,881

Claims. (Cl. 91-111 The present invention relates to an agricultural implement, more particularly to a support bracket for reinforcing a jointer device mounted upon a plow.

It is frequently desirable to employ a device in conjunc tion with a plow to turn over the top surface of the soil during the plowing operation. These devices are known as jointers and may be adapted for use with various types Because the jointer devices also function to cover over any matter which is on the surface of the ground being plowed, they are also referred to as coverboards.

Previously, jointer devices have taken many forms.

The conventional jointer device is essentially a curved cover-board attached to the plow beam immediately forward of the plo-w itself. However, this particular type of device did not prove to be effective in the plowing operation.

In an application having the Serial Number 445,287, and filed July 23, 1954, now Patent No. 2,712,784, the present inventor has disclosed a jointer device which is attached solely to the plow itself. This type of jointer device has been found to have many advantages. However, the present inventor has devised improvements over his previously disclosed jointer device.

In the past, various braces and reinforcing beams have been resorted to in order to enable the jointer device to withstand heavy loads when in operation. These various reinforcing structures, however, have inevitably been rigid due to a positive connection between the jointer device and a supporting member. Consequently, the structure was in most cases cumbersome and did not readily lend itself to rapid adjustment of the positioning of the jointer device.

The present invention discloses a supporting structure for a jointer device. This supporting structure essentially comprises an angle bracket with the horizontal face having an inclined edge. The inclined edge isadapted to engage the plow beam to which the plow is attached. The supporting bracket is adjustably attached to the rear face of the jointer device. Consequently, the jointer device may be adjusted to engage the plow beam for any position into which the jointer device has been fixed.

Support for the jointer device is derivedby the inclined surface of the supporting bracket wedgingly engaging the plow beam. Forces imparted to the jointer device during the plowing operation are, in turn, transmitted to the supporting bracket tothe plow beam. This enables the jointer device to withstand greater forces.

There is no direct connection between the supporting bracket and the plow beam. This results in complete flexibility of the supporting bracket for positioning at any adjustment of the jointer device;

While the plow beam of a conventional plow is a convenient structural element from which support may be derived for the jointer device, it should be borne in mind that teachings of this invention apply with equal force to 2,829,580 Patented Apr. 8, 1958 bracing the jointer device against any other structural members.

The adaptability of the support bracket of this invention is demonstrated by the various jointer mounting structures to each of which the supporting bracket of this invention has been attached.

It is, therefore, the principal object of this invention to provide an improvement in agricultural machinery.

It is another object of this invention to provide an improved arrangement for mounting a jointer device on a plow.

It is a further object of this inventionto provide an arrangement to enable a plow cover-board to withstand greater loads.

It is an additional object of this invention to provide a non-rigid and adaptable bracket arrangement for supporting a jointer device attached to a plow.

Other objects and advantages of this invention will become readily apparent upon reference to the accompanying description when taken in conjunction with the following drawings, wherein:

Figure 1 is an over-all view of a multi-unit plow comprising plows equipped with the support bracket of this invention;

Figure 2 is a top plan View of the supporting bracket and jointer mounting structure;

Figure 3 is a rear elevational view of the jointer mounting structure and supporting bracket;

Figure 4 is a front elevational view of the plow showing the jointer mounting structure and the supporting bracket;

Figure 5 is a rear elevational view of a modification in the jointer mounting structure and illustrating the method of employing a supporting bracket therewith; and

Preceding to Figure 2, plow 11 is of the moldboard type and comprises a plow share 13 and moldboard 14 and a landslide 15 attached to the rear of the plow share 13.

There is a bracing plate 16 which is the reinforcing element between the landslide 15 and the moldboard 14.

The plow 11 has a front, or furrow, face 17, and a rear, or landslide face 18.

The leading edges of the plow share 13 and the moldboard 14 form a cutting edge 19. The top edge of'the moldboard, indicated at 20, is arcuate in the conventional manner of the moldboard plow.

A spacing or reinforcing brace 21 extends: between the upper portion of the brace plate 16 and the rearward portion of the moldboard 14. The brace 21 is secured by means of bolts 22 and 23 at each end thereof.

A jointer device or cover-board 24 is mounted upon the top edge 20 of the plow. It is preferable that the lower edge of the jointer board, indicated at 25, contact the top edge 29 of the plow to prevent any debris from wedging between the coverboard and the plow.

The jointer board 24 is essentially a curved deflector. The forward portion of the jointer board 24 is substantially flush with the moldboard of the plow. The rearward portion of the jointer board curves outwardly over the furrow side of the plow. In addition, the extreme rearward portionof the jointer board is also curved down- I; wardly so as to deflect the plowed dirt into the previous furrow. There are a pair of bolt holes 26 and 27 in the forward portion of the jointer board which are used for mounting the jointer device.

The jointer board mounting structure is clearly illustrated in Figure 3. The mounting structure comprises an angle bracket 28 having a vertical face 29 and a horizontal face 30. The vertical face 29 has a transverse slot 31 therein to accommodate the bolt 23 of the spacing brace. This enables the entire mounting structure of the jointer device to be secured to the plow by means of a single bolt.

The horizontal face of the angle bracket 28 has a longitudinally extending slot 32 therein.

A second angle bracket 33 which has a horizontal face 34 and a vertical face 35 is secured to the horizontal face of the angle bracket 3%) by means of a conventional nut and bolt, indicated at 36. The bolt opening in the horizontal face 34 of the angle bracket 33 comprises a substantially transversely extending slot 3'7 to facilitate the ultimate positioning of the jointer device. I

On the vertical face 35 on the angle bracket 33 is a pair of substantially parallel transversely extending slots 38 and 39. v

The jointer device 24 is secured to the vertical face 35 of the angle bracket 33 by means of a pair of fiat head bolts 40 and 41 which are inserted through the cooperating holes of the jointer board and slots of the angle bracket 33.

An angle supporting bracket 42 is employed to reinforce the jointer device. The supporting bracket 42 comprises a vertical face 43 and a horizontal face 44. The vertical face 43 has a longitudinally extending slot 45 therein to receive the bolt 41. Tightening of this nut and bolt assembly secures the supporting bracket to the angle bracket 33.

The horizontal face 44 of the supporting bracket has an inclined edge, indicated at 46. The edge 46 inclines toward the cutting edge of the plow.

I The horizontal face 44 is substantially trapezoidal and the edge 46 inclines toward the front or cutting edge of the plow with respect to the opposite edge of the trapezoid which opposite edge is the juncture between the horizontal and vertical faces.

When the supporting bracket has been adjusted to its supporting position, as indicated in Figures 2 through 4, the inclined edge of the supporting bracket is essentially transverse to the plow beam 12. Due to the presence of various slotted openings in the angle brackets and the supporting bracket, the supporting bracket may be adjusted to contact the plow beam for any position into which the jointer device may be adjusted. The inclined edge of the supporting bracket enables the bracket to wedge against the plow beam. This enables the jointer device to withstand greater loads during the plowing op-- eration.

The simplicity and effectiveness of the supporting bracket is readily apparent. In addition, the bracket is adaptable to engage other structural elements of the plow.

The elimination of any bolts or other rigid attachment between the supporting bracket and the plow beam results in a completely flexible supporting structure. Furthermore, the entire jointer mounting structure and the supporting bracket are carried by the jointer device. The disassembly of the jointer device from the plow for any reason does not involve any additional connection other than the bolts securing the jointer device to the moldboard of the plow.

Since the contacting edge of the supporting bracket is inclined and transverse to the plow beam there is a certain desirable amount of resiliency in the jointer mounting structure. Concurrently the wedging action of the supporting bracket results in a very effective supporting structure.

In Figure 5 there is illustrated a modification of the 4, joint mounting structure. The adaptability of the supporting bracket enables the bracket to be readily employed with this modification, and other jointer mounting structures.

This modified mounting structure comprises a platelike bracket 47 having a slight bend therein indicated at 48. The bracket 47 is secured to the plow by means of the bolts 49 and 56. These bolts are of the fiat-head type so as not to interfere with the passage of dirt over the furrow side of the plow.

A second bracket 51 essentially trapezoidal in shape is welded along its lower edge to the bracket 47. Vertical slots 52 and 53 are for the purpose of receiving the bolts 40 and 41 employed to attach the jointer device 24. There is a slot 54 opening on the lower edge of the bracket a"; to accommodate the bracing plate 16.

The supporting bracket 42 is similarly attached to the modified mounting structure by means of a single bolt, as described in the structure illustrated in Figures 2 through 4.

In Figure 6 there is illustrated another modification in the jointer mounting structure with which the supporting bracket of this invention may be readily employed.

This modification comprises a plate-like bracket 55 which is somewhat narrower than the bracket 47.

The bracket 55 is secured to the plow by means of a single bolt 56. The trapezoidal bracket plate 51 of the second modification is then similarly welded to the upper edge of the bracket plate 55. The supporting bracket 42 is also similarly attached to the mounting structure.

Thus it can be seen that the present invention discloses an improvement in jointer devices, which enables the jointer device to withstand a greater load during the plow ing operation. The wedge-like action of the supporting bracket of this invention very effectively supports additional loads imposed on the jointer device. The simplicity of the entire structure results in an increased flexibility and adaptability of the jointer device which is desirable and advantageous in plowing operations.

It will be understood that this invention is susceptible to modification in order to adapt it to difiFerent usages and conditions, and, accordingly, it is desired to comprehend such modification within this invention as may fall within the scope of the appended claims.
